Abstract

The lubrication characteristics of surface treated rolls of the chromium plated roll, the TiN coated PVD (Physical Vapor Deposition) roll and the VC coated TRD (Thermo-Reactive Deposition) roll are examined by using the simulation testing machine developed by the author. The coefficient of fraction is measured in order to evaluate the lubricity, and the occurrence of the friction pick up is observed in order to evaluate the anti-seizure property changing rolling speed and reduction in thickness. The experimental results are compared with that of the conventional roll and the conclusions obtained are as follows; (1) the coefficients of friction of the VC coated TRD roll are about half of that of other rolls, (2) the limitation reduction when the friction pick up occurs is significantly greater than that of the conventional roll.
